What is a round robin DNS entry?

Round Robin DNS is a technique in which load balancing is performed by a DNS server instead of a strictly dedicated machine. A DNS record has more than one value IP address. When a request is made to the DNS server that serves this record, the answer it gives alternates for each request.

How do I check my DNS round robin?
